* Switch time_t, ino_t, clock_t, and struct kevent's ident and dataguenther2013-08-131-5/+338
| | | | | | | | | | | | | | | | | | | | members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@

* This patch is mortly art's work and was done *a year* ago. Art wants to thankniklas2005-05-251-1/+5
| | | | | | | | | | | | | | | | everyone for the prompt review and ok of this work ;-) Yeah, that includes me too, or maybe especially me. I am sorry. Change the sched_lock to a mutex. This fixes, among other things, the infamous "telnet localhost &" problem. The real bug in that case was that the sched_lock which is by design a non-recursive lock, was recursively acquired, and not enough releases made us hold the lock in the idle loop, blocking scheduling on the other processors. Some of the other processors would hold the biglock though, which made it impossible for cpu 0 to enter the kernel... A nice deadlock. Let me just say debugging this for days just to realize that it was all fixed in an old diff noone ever ok'd was somewhat of an anti-climax. This diff also changes splsched to be correct for all our architectures.
* This touches only MI code, and adds new time keeping code. Thetholo2004-07-281-1/+70
| | | | | | | | | | | | | | | code is all conditionalized on __HAVE_TIMECOUNTER, and not enabled on any platforms. adjtime(2) support exists, courtesy of nordin@, sysctl(2) support and a concept of quality for each time source attached exists. High quality time sources exists for PIIX4 ACPI timer as well as some AMD power management chips. This will have to be redone once we actually add ACPI support (at that time we need to use the ACPI interfaces to get at these clocks). ok art@ ken@ miod@ jmc@ and many more

* This moves access to wall and uptime variables in MI code,tholo2004-06-241-85/+59
| | | | | | | | | | | | | | encapsulating all such access into wall-defined functions that makes sure locking is done as needed. It also cleans up some uses of wall time vs. uptime some places, but there is sure to be more of these needed as well, particularily in MD code. Also, many current calls to microtime() should probably be changed to getmicrotime(), or to the {,get}microuptime() versions. ok art@ deraadt@ aaron@ matthieu@ beck@ sturm@ millert@ others "Oh, that is not your problem!" from miod@
* First step towards more sane time handling in the kernel -- this changestholo2004-06-211-2/+2
| | | | | | | | things such that code that only need a second-resolution uptime or wall time, and used to get that from time.tv_secs or mono_time.tv_secs now get this from separate time_t globals time_second and time_uptime. ok art@ niklas@ nordin@

* Merge in a piece of the SMP branch into HEAD.art2004-06-091-1/+12
| | | | | | | | | | | Introduce the cpu_info structure, p_cpu field in struct proc and global scheduling context and various changed code to deal with this. At the moment no architecture uses this stuff yet, but it will allow us slow and controlled migration to the new APIs. All new code is ifdef:ed out. ok deraadt@ niklas@

| | | | | | | | | argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@
